Abstract:In this paper, the characteristics of a novel device structure, uniformly doped ultra-deepsubmicron poly-Si barrier modulated thin film transistor (BM-TFT), are investigated and compared with conventional poly-Si TFT. Use of uniform doping provides a solution from problems associated with random dopant fluctuations. The suppression of the leakage current of the TFT by introducing barrier modulation is verified and presented. The device is optimized with respect to channel length, doping of channel, spacer diel… Show more
